We present a framework for investigating wave function spreading in PT-symmetric quantum
systems using spread complexity and spread entropy. We consider a tight-binding chain …

A bstract Using spread complexity and spread entropy, we study non-unitary quantum
dynamics. For non-hermitian Hamiltonians, we extend the bi-Lanczos construction for the …

The complexity of quantum states under dynamical evolution can be investigated by
studying the spread with time of the state over a predefined basis. It is known that this …

Generalized parton distributions (GPDs) are key quantities for the description of a hadron's
three-dimensional structure. They are the current focus of all areas of hadronic physics …

Krylov complexity has recently gained attention where the growth of operator complexity in
time is measured in terms of the off-diagonal operator Lanczos coefficients. The operator …

The dynamics of quantum systems unfolds within a subspace of the state space or operator
space, known as the Krylov space. This review presents the use of Krylov subspace …

We propose to detect signals from quark orbital angular momentum (OAM) through
exclusive π 0 production in electron-(longitudinally polarized) proton collisions. Our analysis …

Krylov complexity has recently emerged as a new paradigm to characterize quantum chaos
in many-body systems. However, which features of Krylov complexity are prerogative of …

We study information scrambling (a spread of initially localized quantum information into the
system's many degree of freedom) in discrete-time quantum walks. We consider out-of-time …

The Forward Physics Facility (FPF) plans to use neutrinos produced at the Large Hadron
Collider to make a variety of measurements at previously unexplored TeV energies. Its …
